Product Description

Square steel: It is solid and bar material.
Square steel can be divided into hot-rolled square steel and cold-rolled square steel; the side length of hot-rolled square steel is 5-250mm, and the side length of cold-drawn square steel is 3-100mm.
Hot-rolled square steel refers to steel that is rolled or processed into a square cross-section.
Cold drawn square steel refers to steel that is cold drawn and forged into a square shape.
Cold drawn square steel is mainly made of alloy structural steel. The main materials are: 15CrMo, 20CrMo, 30CrMo, 35CrMo, 42CrMo, 45CrMo, 15Cr, 20Cr, 30Cr, 35Cr, 45Cr, 50Cr, 40CrNi, 45CrNi, 50CrNi, 20CrNi330CrNi3, 37CrNi3, 12CrNi2, etc.
Square steel materials include A3, 35#, 45#, 55#, 40Cr, 42CrMo, 35CrMo, Q215, Q235, Q345, 16Mn, etc.
